Modified rank-sum nonparametric CFAR in multiple-target situation

Meng Xiangwei

Since the well-known rank-sum (RS) nonparametric constant false alarm rate (CFAR) detector performs robustly in various and complex background clutter, it plays a very important role in radar detection fields. In order to elevate the detection performance of the classical RS nonparametric …

Wilcoxon Nonparametric CFAR Scheme for Ship Detection in SAR Image

Meng Xiangwei

The parametric constant false alarm rate (CFAR) detection algorithms, which are based on various statistical distributions, such as Gaussian, Gamma, Weibull, log-normal,$G^{0}$, and alpha-stable distribution, are most widely used to detect the ship targets in SAR images at present. However, the clutter …

Rank Sum Nonparametric CFAR Detector in Nonhomogeneous Background

Meng Xiangwei

The parametric CFAR detectors maintain a constant false alarm rate (CFAR) with an assumption of a known clutter distribution form. The representative ones of them are the cell-averaging (CA) CFAR, the greatest-of (GO) CFAR, and the ordered statistic (OS) CFAR, etc. In …
